Other claims from this paper (10)
- Intervention effect Most PRE herbicides controlled Palmer amaranth by over 90% at 30 days, apart from atrazine at 64%.
- Intervention effect Three herbicide mixtures controlled 90%–95% of Palmer amaranth at 45 days.
- Intervention effect Two mixtures provided 96%–99% control at 60 days.
- Intervention effect The two mixtures reduced Palmer amaranth density to 2–4 plants m −2.
- Intervention effect The two mixtures reduced Palmer amaranth biomass to 5–12 g m −2.
- Intervention effect Acetochlor/clopyralid/mesotrione produced the highest corn yield in 2020, 12,139 kg ha −1.
- Intervention effect Acetochlor/clopyralid/mesotrione produced the highest corn yield in 2021, 12,093 kg ha −1.
- Intervention effect Palmer amaranth seed production was lowest with acetochlor/clopyralid/mesotrione.
- Intervention effect The tested herbicides showed no corn injury.
- Recommendation The authors recommend two mixtures for early season Palmer amaranth control.
